As far as the profile goes, its standard across all manufacturers in the world. Moreover if there is a design flaw it should affect all the rings but that's not the case here.
How much layer should be removed to De-carb the rings properly ?
@tbuelna, thanks for the exhaustive post.
Firstly little about the images that I have attached in my previous post. The first image of cross section of Ring is a photograph used for marketing purpose it doesn't show the actual dimensions. The second pic was of actual ring that has faced the...
There is wear on traveller as well as ring. Traveller have lower hardness of around 55 HRc while rings have hardness of 62-63 HRc. Thus travellers gets worn out in normal cycle while life of ring is much higher. But in this case while the traveller life is normal, life of the ring is shortened...
Pls check the image that I had attached in the opening post. You shall notice that there is very small contact area between the two components.
When I say worn out, I mean that the contact area that I mentioned above gets uneven and hence the small component that runs over the ring can't run...
Thanks for the prompt replies.
We use 2nd grade tubes and hence I believe that there could be more impurities or other problems that you guys have mentioned. What can I do to ensure that the same doesn't happen again ?
We are manufacturing spinning rings used in Textile Industry. They are made from SAE 52100 or equivalent grade of steel pipes. After machining they are heat treated (marquenching) to 62-63 HRc. Later they are polished using vibratory and centrifugal machines.
We have enclosed a pic which shows...
